Abstract
Extraction of fresh flowers of Jasminum sambac closed bud and fully bloomed flowers were carried out using microwave-assisted hydrodistillation technique MAHD. The chemical composition of the essential oils obtained were analysed by capillary GC and GC-MS. The main chemical compounds identified from the bud and flower oils respectively were E E-a-farnesene 14.36 13.10 and linalool 4.89 1.16. Chemical components usually found in jasmine essential oils such as cis-jasmone benzyl acetate 0.27 benzaldehyde 0.20 and a-gurjunene 0.34 were detected from the closed buds. On the other hand only cis-3-hexenyl benzoate 6.63 and geranyl linalool 7.09 were found in the flower oiL Other components found in the flower oils were hydrocarbons and made up of 23.91 of the oiL From this study we found that the bud oil contained some of the aroma compounds contributing to the jasmine odour. Although the fully bloomed flowers gave a more distinctive aroma it was possible that the volatile compounds could have evaporated prior to the distillation process. Our study showed that MAHD was suitable for extracting essential oil within a short period 1 h 40 min and useful for the rapid identification of essential oil components.
